To fix this issue is to turn off your hardware enabled DEP. PRD Software is currently working on a solution that will work without having to do this, however for the time being, the following work around is the only option available to get the Help Master Pro reports working on a Vista/Windows 7 machine that suffers from this issue.

Run a command prompt as administrator. To do this, click the start menu, select "All Programs", then "Accessories" and right-click on the "Command Prompt" shortcut and choose "Run As Administrator". From here you can use the following command to disable Data Execution Prevention (DEP) with the following command:

bcdedit.exe /set {current} nx AlwaysOff

You MUST restart computer after running the above command. You can always turn it back on again, do the same and run the following:

bcdedit.exe /set {current} nx AlwaysOn

Note: The changes you have made require you to restart your computer before they can effect.

I hope it will helpful for all.
